The adjustment coefficient of health insurance in the successful employment package by the health insurance reform

Purpose: many domestic welfare programs use the amount of health insurance premiums as a way of measuring individuals' income levels for administrative convenience. As health insurance reform has been made, we examines the income level is still appropriately measured by the health insurance premiums for the employment success package as one of domestic welfare program. Methodology/Approach: we investigate whether the upper limit of the premiums of the self-employed health insured is appropriate or not after healthcare reform, which currently calculated by multiplying the insurance premium of the employee based insured by the adjustment factor (1.2). Findings: we examined appropriateness of the adjustment factors by comparing the premiums before and after the healthcare reform by utilizing the national health insurance data as well as Korea Welfare panel data. We found that the new value of adjustment factor (1.0~1.1) is smaller than the current one (1.2). Practical Implications: to improve the equity between the employee and the self-employed insured after the health insurance reform, the adjustment factor should be lower.
